As we’ve been working on bringing Steam to the living room, we’ve
come to the conclusion that the environment best suited to
delivering value to customers is an operating system built around
Steam itself. SteamOS combines the rock-solid architecture of
Linux with a gaming experience built for the big screen. It will
be available soon as a free stand-alone operating system for
living room machines.
Interesting that they’re giving it away to anyone who wants to make a box that runs it.
